Object tracking apparatus and control method thereof

摘要

The present invention discloses an object tracking apparatus including a reference object, an optical sensor and a controller. The reference object has a plurality of light emitting devices, for generating an optical signal. The optical sensor is for detecting the optical signal and generating an identification signal in response to the optical signal. The controller is for generating a control signal according to the identification signal and outputting the control signal to the reference object, thereby adaptively adjusting a light emitting number or light emitting intensity of the plurality of light emitting devices. The present invention discloses a method for controlling an object tracking apparatus.

1. An object tracking apparatus, comprising:
a reference object having a plurality of light emitting devices, wherein the plurality of light emitting devices are sequentially turned on at different timings, for generating an optical signal; an optical sensor for detecting the optical signal and generating an identification signal in response to the optical signal; and a controller for generating a control signal according to the identification signal and outputting the control signal to the reference object, thereby adaptively adjusting a light emitting number or light emitting intensity of the plurality of light emitting devices; wherein, by sequentially turning on the plurality of light emitting devices at different timings, the plurality of light emitting devices form a different shape when the optical sensor and the reference object are relatively rotated with respect to each other at every different rotation angle, whereby the controller identifies a relative rotation between the optical sensor and the reference object.
